Body dark brown; tarsi, bases and apices of tibiae paler; antennal segments I–II & VI–VIII brown, III with basal half pale, IV with basal third pale, V pale except for extreme apex light brown; fore wing banded, with two pale areas, one sub-basally and one sub-apically. Antennae 8-segmented, III & IV each with a long forked sense cone. Pronotum with no long setae, with reticulations irregularly spaced and with internal markings. Mesothoracic endofurca without spinula; methathoracic endofurca with long curved paired arms extending to mesothorax. Metanotum longitudinally reticulate, internal markings on median third, but wanting on lateral thirds; campaniform sensilla absent, one pair of major setae near anterior margin. Tarsi 1-segmented; hind coxae with coiled internal apodeme. Fore wing with setal rows incomplete on both veins. Tergites II–VIII lateral thirds with assymetrical reticles associated with lateral longitudinal striations, internal markings; VIII bearing craspedum medially, but with tooth-like microtrichia laterally; X with incomplete median split. Sternites with transverse reticulation and well-developed craspeda.
Male similar to female in colour but smaller; sternites III–VII each with a small transverse pore plate.
Intraspecific variation
Not recorded.
Genus and similar species information
The genus Caliothrips includes 22 species, of which about half are described from North America. These species have wrinkles or dot shaped markings within the reticles of their body sculpture. The metathoracic furca is distinctive, with long curved paired arms extending to the mesothorax Nakahara (1991). A revised key to Caliothrips species reported to Brazil is given by Lima et al. (2020).
Feeds on leaves. It was observed on bamboo leaves and collected on dead leaves of Arecaeae in Brazil.
Economic importance
No records.
